What is the area of a parallelogram if its length is x+4 and its height is x+3

Mathematics

Area of a parallelogram is:

\sf A=bh

Where 'b' is the base and 'h' is the height. Plug in what we know:

\sf A=(x+4)(x+3)

Distribute(multiply everything in the first parenthesis to everything in the second parenthesis):

\sf x\times x=x^2
\sf x\times 3=3x
\sf 4\times x=4x
\sf 4\times 3=12

So we have:

\sf A=x^2+3x+4x+12

Combine like terms(3x + 4x = 7x):

\sf A=\boxed{\sf x^2+7x+12}

Simplify the expression -3 ÷ (-2/5 ​
Harlamova29_29 [7]

Answer:

7.5

Step-by-step explanation:

To solve this expression, we can use PEMDAS or order of operations.

<u>Parenthesis</u>

<u>Exponents</u>

<u>Multiplication>Division (Depends on which comes first from left to right)</u>

<u>Addition>Subtraction (See Multiplication>Division)</u>

So First, lets solve the <u>Parenthesis</u>. -2/5=-.4

So now, our equation is -3/-.4

There is no exponents or multiplication, so lets just <u>Divide</u>.

-3/-.4=7.5

The solution is 7.5

Hope this helps!

3√5

The distance between two points on an XY plane is calculated using the distance formula, which is employed in coordinate geometry or Euclidean geometry. The x-coordinate, often known as the abscissa, is a point's separation from the y-axis. The y-coordinate, often known as the ordinate, refers to a point's separation from the x-axis. A point on the x-axis has coordinates of the form (x, 0), and a point on the y-axis has coordinates of the form (0, y). We utilize the Pythagoras theorem in this case to determine the separation between any two points in a plane.

Distance formula = √ ( x₁ - x₂)² + ( y₁ - y₂)²

                                = √ 6² + 3²

                                =3√5
